Microbridge Technologies Announces New Electrically Adjustable Resistor Family
Microbridge Technologies, Inc. announced the availability of a new family of low power, low TC re-adjustable resistors designed to compensate and calibrate precision analog circuits.
"There are numerous solutions on the market to improve accuracy and precision of analog circuits," said Bob Frostholm, Vice President, Marketing and Strategic Alliances at Microbridge. "Each existing solution has some set of drawbacks that Rejustors can alleviate such as limited temperature range, limited maximum frequency of operation, requiring power, requiring a laser, and more. Rejustors offer high temperature operation to 125 °C or higher, high frequency operation in excess of 2GHz, requires no power to operate in circuit, has no wiper resistance, and is adjustable to precision levels 0.1% or better."
Microbridge Rejustors have a wide variety of applications. They are suitable for precision analog compensation in military, aerospace and satellite applications. Automotive applications range from optical systems to engine sensors and tire-pressure monitor. As a sealed device, the Rejustor is well suited for operation in harsh and demanding environments. Industrial applications range from simple calibration of power supplies to calibration of sensors of many kinds including photo transistors, pressure sensors and magnetic proximity sensors. Consumer applications include LCD screen adjustments and timing devices. In medical & science, Microbridge calibration techniques are suitable for use in catheter applications. In Semiconductors, Microbridge’s CMOS based technology enables integration of Rejustor calibration and compensation devices for designs that require better precision than fuses, digital potentiometers or laser trimming can achieve.
All members of the low power family are priced at $0.99 at 1,000 piece quantities. Each QFN package contains two Rejustor elements (R1, R2) making it easier to implement divider networks where the TC of the two resistors must be equally matched.
